hi yall, my truck starts up instantly even below 0F but stalls after about 10 sec or idles rough. it restarts after about 10-15 sec of cranking and then runs flawlessly. definitly an air leak. and i feel like its closer to the motor than the tank cuz it stalls so soon. before the issue i had replaced all injectors and got the return line kit. and all that seems solid. wondering if my ip is leaking air and if there is a way to tell before taking it off and sending it to my local fuel pump shop. i ran alot of bio diesel or should i say bio crack this summer and wondering if its chewed holes in the ruber in the ip and if its just now showing up? i tryed soapy water on differnt conections and nothing. any advice on a leaky ip would be great. thanks- skunk

Do you still have the OEM water drain on the firewall........if so jam a 3/8 bolt up the drain hose after draining it or put a pet**** on the line.

There are rubber seals under the cap nuts on the lift pump to filter header line and the filter header to IP line..... See my photo link.

Check out this site for possible other air leak areas too.......

Skidoo or quad fuel line in clear or lt pink should suffice. If you can find it clear TYGON tubing was the best years a go for most fuels etc.
